Frequently Asked Questions

What wellness peptides do you supply?

Our Wellness range includes PT-141 (Bremelanotide), Melanotan II (MT-2), Oxytocin, Thymosin Alpha-1 (TA), LL-37, and Glutathione — covering melanocortin agonists, neuropeptide hormones, immune peptides, and antioxidant compounds.

What is the difference between PT-141 and Melanotan II?

Both are synthetic melanocortin receptor agonists structurally related to alpha-MSH. Melanotan II is a cyclic heptapeptide that acts non-selectively across multiple melanocortin receptor subtypes. PT-141 (Bremelanotide) is a linear analogue derived from Melanotan II with a more selective receptor profile. The two have different molecular weights and CAS numbers.

What purity standard do these compounds meet?

All compounds are verified by HPLC analysis to a minimum purity of ≥98% on a batch-by-batch basis, with a Certificate of Analysis supplied on every order.

Are these compounds GMP certified?

Yes. All compounds in this category are manufactured under GMP and ISO 9001:2015 certified conditions.

Do you offer private label for wellness peptides?

Yes. Custom-branded vials and packaging are available for qualifying wholesale buyers across this category.
